Fresh air + Energy recovery, reducing running cost of cooling or heating system
Super slim design, minimizing installation space
Slim ventilators are designed specially for the projects which have very strict ventilator height requirement, compared with the traditional congeneric products, Slim height is 20% off. Access door is at the bottom so maintenance is much easier.
High energy recovery efficiency
Holtop crossflow enthalpy exchanger is built in the full Eco-slim series Erv, heat recovery efficiency up to 82% in winter, the allowance of moisture exchange between fresh air and exhaust air make a soft indoor temperature and humidity.
1. Choose the proper installation types based on the building structure
2. Determine the fresh airflow required according to the use, size and number of persons
3. Select the right specifications and quantity according to the determined fresh airflow
Example
The area of a computer room is 60 sq. meters (S=60), the net height is 3 meters (H=3), and there are 10 per-sons (N=10) in it.
If it is calculated according to "Personal fresh air consumption", and assume that: Q=70, the result is
Q1 =N*Q=10*70=700(m3/h)
If it is calculated according to "Air changes per hour", and assume that: P=5, the result is
Q2 =P*S*H=5*60*3=900(m3)
Since Q2 > Q1 , Q2 is better for selecting the unit.
As to special industry such as hospitals (surgery and the special nursing rooms), labs, workshops, airflow re-quired should be determined in conformity with regulations concerned.
